D3 v5 Zoomable Sunburst

D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes hierarchical data from the Flare dataset, representing the size of each node through the arc’s angular width and radial extent. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions applied via `transition.attrTween` and `d3.interpolate`. The visualization uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to generate SVG paths and labels, with `d3.scaleOrdinal` and `d3.interpolateRainbow` providing color encoding. The Observable HQ standard library’s `require` method loads the data from the `@observablehq/flare` module.

D3 v5 Zoomable Sunburst

This D3 v5 zoomable sunburst chart visualizes the hierarchical structure of the Flare software project, using nested arcs where each ring represents a level in the tree and arc angles are proportional to each node's value. The example, ported from an Observable notebook, loads the data from the `@observablehq/flare` library and renders it using SVG. User interactions trigger the `clicked` function, which sets new target values for the `d3.partition()` layout and uses `g.transition().duration(750)` along with `attrTween` on the path elements to animate the zoom across its layered structure.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the structure of a hierarchical dataset, using nested arcs to represent the flare data from Observable’s `@observablehq/flare` library. Each level of the hierarchy is depicted as a ring, with arc segments sized proportionally to the data values. Clicking on a segment triggers an animated transition using `transition.attrTween` and `d3.interpolate` to smoothly re-center the view on that node, showing its children in greater detail. The visualization is rendered with SVG inside a circular partition layout, and the code uses `d3.hierarchy`, `d3.partition`, and `d3.scaleOrdinal` with the `interpolateRainbow` color scheme to distinguish top-level categories.

D3 v5 Zoomable Sunburst

This zoomable sunburst visualizes the hierarchical structure of the Flare dataset, displaying nested arcs whose size and color encode node values and category. Users click any arc to zoom into that subtree, with smooth 750-millisecond transitions animating arc paths and labels via `d3.transition` and `transition.attrTween`. The code uses D3 v5’s `d3.hierarchy`, `d3.partition`, and `d3.arc` to compute and render the SVG layout, while a rainbow color scale distinguishes top-level branches. Data loads asynchronously from the Observable Flare module using `observablehq/stdlib`.

D3 v5 Zoomable Sunburst

This zoomable sunburst chart visualizes hierarchical data, displaying nested nodes as concentric arcs with color-coded categories and interactive labels. Clicking an arc zooms into that subtree, while clicking the center circle returns to the root. The visualization uses D3 v5’s `d3.partition` layout, `d3.arc` for path generation, and `d3.transition` with `attrTween` for smooth animated updates. Data is loaded from the `@observablehq/flare` dataset via the Observable stdlib, which the code fetches using `require()` before rendering the SVG.

D3 v5 Zoomable Sunburst

A zoomable sunburst diagram displays the hierarchical structure of the Flare dataset, with nodes sized by value and colored by top-level category. Clicking a ring zooms into that subtree while decreasing visible depth. Built with D3 v5, it uses `d3.hierarchy`, `d3.partition`, and `d3.arc` for layout and rendering, with transitions via `transition.attrTween` to animate arc geometry and labels. The SVG visualization imports data through the Observable stdlib and includes interactive hover tooltips.

D3 v5 Zoomable Sunburst

The D3 v5 Zoomable Sunburst shows a hierarchical dataset of the Flare visualization library (loaded via the @observablehq/flare module) as a multi-ring sunburst chart. Clicking an arc zooms in to reveal its children, with smooth transitions applied to the arcs and labels via `transition.attrTween` and `d3.interpolate`. The visualization is rendered as SVG, uses `d3.hierarchy` and `d3.partition` for layout, and `d3.scaleOrdinal` with a rainbow palette for coloring top-level categories.

D3 v5 Zoomable Sunburst - PD

This interactive zoomable sunburst visualization displays the hierarchical structure of the Flare dataset, with each ring segment sized by its value. Clicking an arc zooms into that node, using smooth animated transitions to refocus the layout. The code employs D3 v5’s `d3.hierarchy` and `d3.partition` for layout, `d3.arc` for path generation, and `transition.attrTween` to interpolate between states. Color is assigned via a rainbow scale, and labels rotate radially with `d3.interpolate`-based tweening. Data loads from the `@observablehq/flare` package through the Observable stdlib.
